Two in one transforming yo-yo! The Aero-Yo Shuriken 2.0 is a super fun yo-yo and an innovative solution for beginners. It can be used as a string trick (1a) or looping (2a) yoyo. The perfect way to begin to learn the basics of two yo-yo styles with one yo-yo! Ho does it work? Out of the package, the yo-yo has a butterfly shape, a small bearing and long lasting rubber response system. It has amazing response, just what beginners need! It’s not too responsive and not too unresponsive. Comes back easily to the hand whenever you want it to and still unresponsive enough to do more advanced tricks like the Mach5, Cold Fusion and Gyroscopic Flop with ease! Try it to believe it! Turn your 1A yoyo into a 2A yo-yo without even removing the axle! When you are ready to transform your yoyo and learn some looping tricks, turn the two halves apart. Remove the bearing, turn the axle clockwise so that it will go through the yo-yo and push out the spikes. Now insert the bearing on the other side where the axle is showing and put the two halves together and boom, you have a classic imperial shaped looping yoyo with star-brush response! We recommend this yoyo for everyone’s collection.
